I had perpetual Propane smell in my old trailer for one season. I found that the oven was set to pilot just slightly. Once I turned the selector to off we never got the smell again. I spent hours on multiple trips trying to track that leak and it was something simple and basic. Good Luck, I hope it is an easy fix.
